But the "receiving" ISP is only receiving the data because its users asked for it. It doesn't make a difference if the data comes from a Spotify server or from a PC. It's still the same amount of data being transferred.

Receiving data over a transit connection may be more expensive than from a CDN. In DOCSIS networks, P2P also tends to introduce last-mile upstream congestion which is expensive to fix.

The last mile problem is presumably exasperated by P2P users being mostly consumers, rather than businesses, and therefore paying next to nothing for the connections.

The very fact that the Spotify team was willing to publish this paper demonstrates how confident they are in their offering. Spotify is (albeit at a high level of abstraction) telling competitors exactly how its service works! They’re begging Amazon and Google and Apple and the likes to copy their model. Those are some cojones.

What an odd question. ISPs sell a link to their customers, they don't need to be okay with it.

the "link" (guaranteed amount of bandwidth) they sell to you as a home customer ends with the next hop.

And so does the consumer's concern at that point, who is paying for a link with a guaranteed bandwidth. How they accomplish that beyond my home wall jack is simply not my concern, just like I don't care where the electricity in my sockets is being sourced from.
